Abstract

This study was carried out in the Chungnam National University grassland experimental field from October, 2007 to December, 2009 in order to find out the growth characteristics, seasonal anthesis distribution and botanical composition of the wildflowers which were altogether composed of 70% sheep fescue and 30% wildflowers. The experimental wildflower species contained 30 species in total to which sheep fescue (fundamental turfgrass), 8 native wildflowers, and 22 introduced wildflowers belonged. At the time of the anthesis of the wildflowers, the average length was 28.3 cm one year later and 34.5 cm two years later. They bloomed out into eight colors, but into simplified two colors during August, September, and October. The blooming season leant toward May and June and from August there was lots of difficulty in the wildflower blooming and the maintenance of their consistency. Especially, at the age of two (2009), the annual wildflowers after wintering were reduced but on account of domestic wildflowers the color, seasonal distribution, and consistency showed improved compared with those of one-year-old wildflowers. The annual ration of wildflowers, sheep fescue, and weed came to 25%, 61%, and 14% each one year later (2008) and 24%, 62%, and 14% each two years later (2009). Based on this result, cultivating wildflower grassland in the combination of native wildflowers and introduced wildflowers is estimated to be the proper method in the aspect of interaction.
